Wince Bluetooth control API functions

You can also directly use the existing API functions bthsetmode () and bthgetmode () for Bluetooth settings ().
The two functions are defined in: bthutil. h, and then the dependent lib Library: bthutil. Lib needs to be added.
Int bthsetmode (
DWORD
Dwmode
);

Int bthgetmode (
DWORD *
Pdwmode
);

Return Value
Returns error_success on success or returns an error code on failure.

Among them, there are three dwmode values. One is disabled, and two are opened: one is searchable, and the other is not searchable.

The value is defined as follows:

Enum bth_radio_mode {bth_power_off, bth_connectable, bth_discoverable };
